Keith Browning Posted November 9, 2009 Share Posted November 9, 2009 Am I the only tech that spills fuel every damn time I change the secondary fuel filter on these things? As you know the filter lid is quite tall and fuel has nowhere to go but over the edge... now I have tried opening the water drain... replacing the primary filter first but I still have a full housing on top! Yeah, I use a turkey baster to empty the housing before the new filter goes in. Other wise I usually add insult to injury. Any tips or experiences?

gasgasman Posted November 11, 2009 Share Posted November 11, 2009 The engineer that designed that wiring harness that runs right behind the frame mount filter ought to get the Nobel Piece prize. For piece of crap!! Quote Link to comment Share on other sites More sharing options...
Aaron Posted November 13, 2009 Share Posted November 13, 2009 The last time I remember NOT spilling fuel, it seems to me that I had left the filter OUT of the HFCM, and when I pulled the filter out of the top, it drained...but I can't be 100% certain, it was a LONG time ago.

BrunoWilimek Posted November 14, 2009 Share Posted November 14, 2009 I read a tip on pro-tech that I now use and it seems to work. I remove the top filter first, not re-installing the new one yet. Then I lift the truck on the hoist and change to lower one. After lowering the truck, the fuel level in the secondary housing has dropped, so installing the new filter is problem free, but I leave the cap unscrewed so I can monitor the fuel level in the housing. This is where it gets a little tricky. I cycle the key to the run position for a few seconds a few times until the fuel level rises to mostly fill the housing without overflowing it. A second person to watch helps. When the fuel level is high enough to just fill the housing without overflowing when tightening the cap, I then tighten the cap, and usually startup is ensured, but to be certain, I cycle the key once more and bleed the air at the valve stem.

fabfoes87 Posted December 14, 2009 Share Posted December 14, 2009 anyone have a hard time with starting the 6.4 after filter replacement? I replaced both filters, and now have no start. I know you have to bleed the air from the low pressure system but trying with no joy. Might be a stupid question for all you brianiacs out there but any tips? Thanks Quote Link to comment Share on other sites More sharing options...
Jim Warman Posted December 14, 2009 Share Posted December 14, 2009 Filter replacement... pretty much what Bruno does... Before starting the truck... key on for 20 plus seconds... do that six times. I rarely have any problems... If it starts and then stalls... go get the shop foreman (or pretend to) and by the time you get back, it will likely start and run like a champ...

DwayneGorniak Posted December 14, 2009 Share Posted December 14, 2009 I pretty much do what Bruno does, but just a wee bit different. Pull out the secondary filter and leave it out, then go and do the primary filter, then put the secondary filter in the housing without the lid on it, get an apprentice to cycle the key on untill fuel is about 3/4 the way to the top and yell....Whhhhoooooo! Put the lid on and cycle the key twice and your Taco Bell (Good to Go). Quote Link to comment Share on other sites More sharing options...
cbriggs Posted December 14, 2009 Share Posted December 14, 2009 I made a bleed tool out of some old fuel guage parts, fits on shrader and has a 24" hose and shutoff valve. Thread it on, let it run koeo once, fire up with it open for 20 seconds or so, then remove. Quote Link to comment Share on other sites More sharing options...
